AMERICAN LEPIDOPTERA. 63 



with white below the middle. Orbicular black, punctiform, always present on 

 the white shading and usually well niai'ked. Eeniform gray or blackish, oval, 

 not well marked, ofteu lost in the dark shading. Secondaries mostly blackish, 

 becoming pale basally and with a dusky discal lunule. Beneath curiously mot- 

 tled with black and yellowish white. Primaries black, inner margin, part of 

 costa, part of terminal space, an ante-apical blotch and a triangular discal blotch 

 pale. Secondaries mostly pale; a black outer band, from which a central ray is 

 sent to the base; a discal lunule, a half band from the costa, and one or two rays 

 from the base, all blackish. 



Expands 21-2(5 mm. ^ .84-1.04 inches. 



Hab. — Kansas in May; Arizona; Texas, March, May, Septem- 

 ber, December. 



Eight specimens, representing both sexes, are under examination 

 and no two of them are alike. The two extremes are : a base un- 

 interruptedly white to the outer portion of median space, and a 

 wing solid gray, with two quadrate costal patches, a whitish longi- 

 tudinal shade over subraedian vein, and a whitish patch on internal 

 margin. Between these extremes all possible intermediate forms 

 occur. 



In wing form and general habitus this species resembles flavipen- 

 nis, as it does also in the venation of the secondaries. Vein 6 seems 

 to be a little more remote from the median, but otherwise there is no 

 difference, and this is hardly appreciable in some cases.

 Head and thorax glistening chocolate-brown. Abdomen white. Primaries 

 with an oblique chocolate patch at base, narrow on costa, extending to about one- 

 fourth on inner margin; beyond this, white to the outer part of median space. 

 At the outer portion of wing is a deep, dark mossy green band, extending from 

 just within the hind angle, first a little incurved, then outcurved, to the apex, 

 leaving the terminal space white. A narrow denticulated metallic blue line 

 runs through this shade, representing the s. t. line. A yellow spot at outer third 

 of costa sends an oblique yellow shading outwardly to join the baud at about the 

 place of the reniform. This is variably evident and is about the only variable 

 feature in the wing. The ordinary spots are wanting. Secondaries white, with 

 a variably distinct outer band, sometimes complete, more rarely starting broadly 

 at the apex and narrowing to nothing a little before the anal angle. Beneath, 

 primaries blackish, except along the margins. Secondaries white. 

 Expands 24-28 mm. = .96-1.12 inches. 



Hah. — Texas, April to June. 



Eight examples, evenly divided as to sex, are before me and I 

 have seen numerous others. This is one of those satisfactory spe-
